PUMPING POWER.

Application filed January 2, 1923. Serial No. 610,398.

T 0 all whom it may concern:

Be it known that we, 1min! G. COREY, REMI C. KNmnT. and Louis F. CHAMPION, citizens of the United States, residing the said Conny at Bcrkelcyin the county of Alameda and State of California, and the said KNIGHT and CHAMPION at Oakland, Alameda County, State of California, have invented certain new and useful Improvements in Pumpin Powers, of which the following is a speci cation..

Our invention relates to the class of pumping powers for operating a group of wells from a central point, by means of pull lines or other transmitting connections.

The essential object of our invention is to eliminate all strains, except torque, from the prime mover and driving-mechanism, thereby permitting the device to be made compact and relatively small but of high efficiency, and requiring small housing room, which enables it to be most advantageously placed with its driving mechanism below the surface of the ground and its operating head at or near the surface, thus locating the plane of working effort close to the ground and avoiding overhead braces and supports.

With this object and its several advantages in view, our invention consists in the novel pumping power which we shall hereinafter fully describe by reference to the accompanying drawings, in which Fig. 1 is an elevation of our pumping power.

Fig. 2 is a plan of the same.

Fig. 3 is a vertical cross section and elevation, enlarged, of the operative or floating head of the power, showing its support independent of and its flexible coupling with the driving mechanism.

It is to be understood that in these drawings and the following specification, we have disclosed our pumping power in but one of its forms and that changes may be made, particularly with regard to the prime mover and driving mechanism without departing from the scope and spirit of the invention as defined by our claims.

Referring to Figs. 1 and 2-the numeral 1 indicates the prime mover, as for example an electric motor, having a starting clutch 2 and a shaft 3.

- 4 is a hollow column, forming a casing for the driving mechanism, comprising the main shaft 5, bevel gears 6 and the various reduction gears 7 As these features form part of our invention, only in so far as they indicate a prime mover and suitable reduction driving mechanism, they need not be further elaborated, and moreover their arrangement here shown discloses only a convenient method of adapting the power to a horizontal drive, though other forms and types may be substituted.

The main shaft 5 on the slow speed side of the reduction gears is connected to the shaft El of the operating head by a flexible coup- 1mg. The head shaft 8,-the flexible coupling and the operating head, which by reason of its independent mounting and its flexible connection with the driving mechanism is, relatively to said mechanism, a floating head, are best seen in Fig. 3 to which reference may now be had.

9 is the head-support which as shown in Fig. 1 is independently installed at or near the surface of the pit P in which the prime mover and driving mechanism are housed. Resting upon and bolted to the support 9 is the base 10 of a vertically disposed bearing 11. Through this hearing 11 passes the power head shaft 8. A thimble 12 is keyed at 13 to shaft 8 and is held by a nut 14. The thimble 12 fits down over and is adapted to. rotate about the exterior of the bearing 11, and said thimble carries one or more eccentrics 15, fitted with straps 16 to which are connected the clevises 17 for thepull lines, not shown, extending to the pumping mechanisms of the wells to be operated by the pump power.

The flexible coupling rotatively connecting the head shaft 8 and main shaft 5 of the drivin mechanism, and which renders the operatlng head of the device a floating member, may be of any suitable nature. In Fig. 3 it is shown as comprising a ring 18 about the upper end of the main shaft 5, a ring 19 about the lower end of the head vshaft 8, said rings being joined by bolts 20, a collar 21 on the head of the shaft 5, a collar 22 on the foot of shaft 8, and balls 23 seated in vertically disposed grooves in the adjacent surfaces of the rings and collars.

It will now be readily seen that by reason of the independently supported or floating head, all shock and strain from the wellpum pull-lines, are eliminated from the turning mechanism, except torque, and the whole device may be made relatively small member carried by sai y and compact and conveniently located with 2. A pumping power comprising a vert1 cally dis osed driving member; a head member inc uding a non-rotatable support mount-edindependently of the driving member, a vertically disposed shaft rotatably carried by said support in axial alignment with the driving member, an eccentric care and a flexible coupling ried by said shaft in fixed relation thereto; between said shaft and the driving member.

3. A pumping power comprisinga driving mechanism including a rotatable shaft; a head member supported independently of said driving mechanism, and including a rotatable shaft; a flexible coupling between the two shafts; and an eccentric carried by said head shaft in fixed relation thereto.

4. A pumping power comprising a driving mechanism including a rotatable shaft; a head member including a non-rotatable support mounted independently of the drivling mechanism, a shaft rotatably carried by said support, an eccentric carried by said shaft in fixed relation thereto; and a flexible connection between the two shafts. 5. A pumping power comprising a driving mechanism including a rotatable shaft; a head member including a non-rotatable support mounted independently of the driving mechanism, a shaft rotatably carried by said support in axial alignment with the shaft of the driving mechanism, and an eccentric carried by said head shaft in fixed relation thereto; and a flexible connect-ion between the two shafts.

6. A pumping power comprising a drivaceaaeo ing mechanism including a rotatable shaft; a head member includin a non-rotatable support mounted indepen ently of the driving mechanism; a rotatable thimble carried by said support, and a shaft carried by said thimble; a flexible connection between the two shafts; and power transmission devices associated with and driven by the thimble of the head member.

7. A pumping power comprising a driving mechanism including a rotatable shaft; a head member including a non-rotatable support mounted independently of the driving mechanism; a rotatable thimble carried by said support, and a shaft carried by said thimble; a flexible connection between the two shafts; and an eccentric associated with 1 and rotated by-said thimble.

8. A pumping power comprising a driving mechanism including a vertical rotatable shaft; a head member including a non-rotatable support positioned above said" driving mechanlsm and mounted independently thereof, a rotatable thimble carried by said su port, and a shaft carried by said thimble; a exible connection between the two shafts; and power transmission devices associated with and driven by the thimble of the head member.

9. A pumping power comprising a driving mechanism including a casing, a rotatable shaft projecting therefrom, power transmitting connections within said casing, and

means for supplying power to said shaft through said connections; a head member including a non-rotatable-support positioned above said'driving mechanism and mounted independently thereof, a rotatable thimble carried by said support, and a shaft carried by said thimble; a flexible connection between the two shafts; and power transmission devices associated with and drivenby the thimble of the head member.

In testimony whereof we have signed our names to this specification.
